Erm, I would disagree and say that yes, it is her fault. She doesn't know her job properly. IF she had the proper training etc. she would (should) have known that it is fairly common for clients to 'resist' or not want to get well.

There are myriad reasons for this (and there was a perfect opportunity for her to explore with you what that was about - for you specifically) but in no way does it indicate that such clients no longer need therapy.

It seems like the therapy she does is very superficial. She took you literally, showing (for a T) a lack of knowledge of how the psyche works. So, it's not about you not 'explaining super well' but her being limited as a T & not going deeper when she was offered the opportunity to do so.

No wonder you feel heartbroken and abandoned. She completely missed you and what you were trying to say to her. It's on her, not you.
